This paper presents a novel data-hiding scheme based on side-match vector quantization (SMVQ). While encoding a block of an image, a traditional SMVQ data-hiding scheme only considers the neighboring pixels of the block to be encoded to produce a state codebook, and then uses the index of the closest codeword in the state codebook to represent the block. The major problem of the traditional image...
Organophosphate (OP) poisoning is a worldwide concern. Several factors have been identified to predict outcomes of OP poisoned patients. This study focuses on the relationship between the trend in Serum cholinesterase (SChE) activity and its clinical outcome in acute OP poisoned patients.We retrospectively reviewed the medical records of all adult acute OP poisoned patients that visited the Emergency...
We have designed a maximum likelihood fitter using the actor model to distribute the computation over a heterogeneous network. The prototype implementation uses the SALSA programming language and the Internet Operating System middleware. We have used our fitter to perform a partial wave analysis of particle physics data. Preliminary measurements have shown good performance and scalability. We expect...
